Additional task-related features and issues within Microsoft Teams for business
For those who are still having this issue, at this current point in time you still can't delete a plan directly through teams, but you can do it through the Planner web app in the browser. I was able to do so by following these steps:
- Go to the Teams channel where the plan is located.
- Click on the dropdown of the "Tasks" tab at the top of the channel (or whatever plan you are trying to delete).
- Click "Open in browser" to open the plan in your browser.
- Click the 3 dots at the upper middle of the screen, next to Grid, Board, Charts, Schedule, Timeline.
- Click "Plan Settings".
- At the bottom of the side pane, click "Delete this plan".
- Check "I understand that this plan and all of its tasks will be permanently deleted", then click "Delete".
Good luck with it,
Grant
